Chicago Board of Trade soyabean futures fell on Thursday for a fifth straight session, with the spot March contract hitting a six-week low on expectations of a big South American soya harvest and an expansion in US plantings, traders said. CBOT March soyabeans settled down 11-1/4 cents at $10.11-1/2 per bushel after dipping to $10.10, the contract's lowest since January 12. The contract fell through support at its 100- and 200-day moving averages.

The USDA at its annual outlook forum projected US 2017 soyabean plantings at 88.0 million acres, above an average of trade expectations in a Reuters poll for 87.6 million. Agroconsult, a Brazilian consultancy, on Wednesday raised its forecast for the country's 2016/17 soya crop to 107.8 million tonnes, up from its February 8 estimate of 105.3 million. CBOT March soyameal followed soyabeans lower.
